Note
1. Emerson Process Management recommends that the valve manufacturer supply the maximum required torque
values (Including any adjustments or suggested safety factors for valve service conditions or application).
Additionally, the valve manufacturer must identify at which position(s) and direction(s) of rotation
(Counter Clock Wise or Clock Wise) these maximum requirements occur.
2. If in doubt, or you require any assistance with sizing actuators, do not hesitate to contact your
nearest Emerson's Valve Automation Division representative.
